Question

a) If x & y vary inversely and y = 45. Find x when constant of variation is 8 ? Ans :-​

Answer 1

Answer:

8/45

Step-by-step explanation:

Two quantities x and y are said to vary in inverse proportion if

xy = k -----------( 1 )

where k is a constant.

according to our problem

y = 45 ,

k = 8

put these values in ( 1 ),

xy = k

x × 45 = 8

x = 8 / 45

if y = 45 then x = 8/45
